Using cramer’s rule, what is the value of x in the system of linear equations below? x+3y=16 3x+y=8

 The required value of x is 1.

Step-by-step explanation:  We are to use the Cramer's rule to find the value of x in the following system of equations :

By Cramer's rule, we get

where

Therefore, we get

Thus, the required value of x is 1.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
